The importance of fuel cell system simulation platform At present, an electric-electric hybrid solution using fuel cells and power batteries as energy sources has become a main power architecture of FCV. The fuel cell electric hybrid solution must not only ensure the high stability and reliable output of the fuel cell stack, but also efficiently distribute the output power of the fuel cell and the power battery. At the initial stage of development, the establishment of a fuel cell system simulation platform in the laboratory plays an important role in the rapid research and verification of power system reliability, energy distribution strategies and algorithms. Compared with power batteries, fuel cells have obvious advantages in terms of lightweight, long endurance and low temperature characteristics, and can solve the problem of slow charging (hydrogenation). At present, the electric-electric hybrid propulsion scheme with fuel cell-lithium battery as the power source has gradually at...
